Horizontal axially split pump for guiding leaked liquid

Abstract

The invention relates to a horizontal axially split pump, in particular to a horizontal axially split pump for guiding leaked liquid, and solves the problem that the sealing mode of an existing horizontal axially split pump cannot give consideration to simple process, low cost and good reliability. At least one flow guide groove is formed in each of two sides of a volute chamber flow channel on the axially split surface of a pump body; or at least one flow guide groove is formed in each of two sides of the volute chamber flow channel on the axially split surface of a pump cover; or at least one flow guide groove is formed in one side of the volute chamber flow channel on the axially split surface of the pump body, and at least one flow guide groove is formed in the other side of the volute chamber flow channel on the axially split surface of the pump cover. The number of the flow guide grooves in the two sides of the volute chamber flow channel is equal, and the flow guide grooves in each side are formed between bolt holes in the side and the volute chamber flow channel. The starting end of the flow guide groove on each side is close to a mechanical sealing cavity, and the leading-out end of the flow guide groove is communicated with a suction cavity. By means of the mode that dredging replaces blocking, leaked liquid is guided to the suction cavity through the flow guide grooves, and the sealing difficulty of the axially split surface of the horizontal axially split pump is reduced.

Description

technical field [0001] The invention relates to a horizontal split pump, in particular to a horizontal split pump for realizing leakage liquid diversion. Background technique [0002] The horizontal split pump has the structural characteristics of quick replacement of rotor parts and wearing parts, which can shorten the maintenance time of the pump, and the split face sealing technology and sealing ability are one of the main aspects that limit the application of horizontal split pumps. At the same time, the main manifestation of the leakage of the split pump is the leakage of the split face. [0003] At present, the main methods of split face sealing are hard-to-hard metal seal, flat gasket seal, glue-coated seal, etc. These three methods of sealing have certain effects on split face sealing. Hard-to-hard metal seals require extremely high technology and processing capabilities, and general technology is difficult to achieve; flat gasket seals require high processing techn...
